FASTENER Application filed January 14', 153529. Serial No; 332,387.

' This invention relates to storm sash fasteners, and the primary object is to provide means of a novel, efiicient, and practical nature for operatively connecting a customary outwardly swinging storm sash with the usual lower sliding sash of the permanent house window whereby, when the inner window is raised the storm sash will be projected, and when the inner window is closed the storm sash will be drawn in and closed also. Brief consideration to a mechanism which will perform this action shows that its many advantages are of considerable value and importance. The usual forms of storm sash fasteners, or at least those that have come to our attention, operate entirelyindependently of the sliding sash, i. e., the storm sash is always secured in either a wide open or closed position, witha result that it is usually, or at least frequently left open, even when the inner window is closed, with a result that it has no heat insulating value and does not accomplish the object for which it is primarily intended. To overcome this objection; to provide means for insuring a complete closing of the outer window when the inner window is closed; and, to provide means for regulating the open position of the storm sash in proportion to the extent to which the inner window 39 is opened, we have designed and perfected the device shown in the accompanying drawing,

wherein: i

Fig. 1 is a sectional elevation through the lower portion of a window frame and adjacent portions of the lower sliding sash and the storm sash, with one of the improved fasteners applied thereto, with both sashes closed. i p Fig. 2 is a sectional plan view, as seen when 40 looking down upon the structure shown in Fig. 1, but with both sashes open.

Referring to the drawing more particularly and by reference characters A designates the sill of a window frame having side plates B pro ided with parting strips C, stops D between which and the strips C the lower inner window G slides, and outer stops E, between which and the strips C the upper inner window (not shown) slides, and against which 0 stops E the stormsash F closes when drawn into'the frame,said storm sash being hingedly hung from the upper end of the window frame in anywell known or approved manner. z

At both sides of the window (although only one side is shown) we connect the sashes F and G by bars 3, the same being pivotally secured, to the respective windows, by brackets 4i and 5. Each of these bars is slightly inclined from the vertical, and the lower end is secured to the sliding sash, while the upper end is secured to the swinging sash, F with a result that when the window G is raised it will force the sash F outwardly, as

indicated by dotted lines in Fig. 1. WVhen the bar 3 reaches the horizontal position the sash F has of course reached its outwardly swinging limit.

At an intermediate point between its ends the bar Sis-provided with a rivet or pin 6, 9 that slidably and pivotally engages the slot 'Z in the depending end of a link 8, the upper end of which is pivot-ally connected to a bracket 9'secured by screws 10 to the window frame B. As the window G is pulled up from its closed position the pin 6 rises in the slot 7 during the initial outward movement of the sash F. When the pin 6 reaches its up ward limit in the slot 7 the link 8 starts to swing outwardly with the pin, as indicated by the dotted lines, and in doing so is associated with the bar 3 to produce a toggle action whereby the inward weight or pressure of the storm sash will be distributed in part to the fined bracket 9, thus greatly relieving tl e stress on the window sash G, and more firmly bracing the sash F against the wind. Conversely, when closing the windows the pin 6 stops in the lower end of the slot 7, and,as-the sash G approaches its fully closed position there is substantial inward pull on vthe bar 3 by the permanently anchored link 8, which tends to pull the pin 6 into alignment between the pivots of the brackets 5 in the spirit and scope of the appended claim.

Having now therefore fully disclosed our invention, What We claim to be new and desire to protect by Letters Patent is:

A fastener for the swinging storm sash of :1- window having upper and lower sliding sashes comprising a rigid one piece bar pivotally connected at its outer end to the storm sash and at its inner end to the lower sliding sash, and a link member pivotally secured at one end to the frame of the Window, the other end of the link being slidnbly and pivotally connected to the bar it a point hetween the ends of the latter.

Signed this 11th day of January, 1929, at Faribanlt, Minnesota.
